Hissing under boost

Hissing under boost
So I had this problem of a weird hissing noise under boost. I just converted to simplified sequential and replaced all the vacuum lines hoping that this would solve the problem.
I took the car out last night for the first time, and the noise is still there. The weird part about this noise, is that it sounds like its rushing air out of the vent near the vents on the door. There is definitely no air coming out though. At first I thought it was a huge boost leak, but the area of the sound just makes no sense to me.
Is it possible that it's just turbo noise and the acoustics travel around the engine bay to that area? My passenger said he heard the same thing on his side in the same area.
The car is also maxing out ~6-7 psi. I did some searching and it looks like the "pills" inside some of the lines were the cause if they were missing. I found 2 while I was doing the conversion, and replaced them in the same orientation. Are there more than 2 or could this 7 psi max be something else?
Thanks in advance.
